Which Has the Better Warranty, Pink Batts or Earthwool?

Pink Batts carries a consumer lifetime warranty, while Earthwool carries a 50-year product warranty, and the practical difference for most homeowners is minimal since both are expected to last the life of the home.

Is Bradford Gold Better Than Earthwool or Pink Batts?

Bradford Gold, Earthwool and Pink Batts are all high-quality glasswool insulation brands, and the right choice generally comes down to handling preference, budget and specific application.

Pink Batts vs Earthwool: Which Insulation Is Better?

Q: Does Earthwool Attract Termites or Vermin?

No, this is a common myth. Earthwool uses a natural, formaldehyde-free binder that does not attract termites, vermin, or other pests.

Q: Should Ceilings or Underfloor Be Insulated First?

Ceilings, generally, since roof spaces typically account for a larger share of a home's total heat loss and heat gain than underfloor areas.

Pink Batts and Earthwool are two of the most widely used insulation brands in Australia, and both are genuinely high-quality glasswool products made from sand and recycled glass. The differences between them come down to handling, fit, warranty and a few practical details that matter once installation day arrives.

What's the Core Difference?

Both products are manufactured in Australia — Pink Batts by Fletcher Insulation, Earthwool by Knauf Insulation, which also operates local Australian manufacturing facilities. The most obvious difference is colour: Pink Batts get their signature pink tone from added dye, while Earthwool’s natural brown colour comes from having no added dyes or formaldehyde in its ECOSE® Technology binder. The colour itself has no effect on thermal performance.

Thermal Performance

Once installed, an R2.0 wall batt delivers the same thermal protection whether it’s branded Pink Batts, Earthwool, or any other glasswool product at that R-value. R-value is what determines resistance to heat flow, not the brand behind it. Both ranges are available across a wide spread of R-values to suit different climate zones and NCC requirements.

Handling & Itch Factor

This is where Earthwool has built most of its reputation. Its ECOSE® Technology binder is formaldehyde-free and produces a noticeably softer, low-itch product compared to traditional glasswool. Pink Batts uses a more conventional glasswool manufacturing process, which tends to be itchier to handle, particularly during longer installation jobs.

Fit & Installation

An often-overlooked factor is how well a batt “stands” in the wall cavity without sagging. Pink Batts has a firmer, more rigid consistency, which gives it a genuine edge when wall studs aren’t spaced perfectly — it holds its position with less risk of sagging over time. Earthwool’s softer consistency is more comfortable to handle, but can require more careful fitting in wider or uneven cavities to avoid gaps.

Odour

Older-style glasswool insulation is known for retaining a noticeable smell, especially in confined roof spaces. Earthwool is genuinely close to odourless, while Pink Batts and other conventional glasswool products tend to retain at least a faint odour, usually only noticeable up close. For anyone particularly sensitive to smell, Earthwool holds a real advantage here.

Warranty — the Clearest Point of Difference

Earthwool is backed by a 50-year product warranty. Pink Batts is backed by a consumer lifetime warranty. It’s worth noting that these warranties generally cover the batt remaining structurally intact rather than guaranteeing a specific thermal performance figure over time — so warranty length is a useful comparison point, but not the only factor worth weighing.

Which Should You Choose?

Prioritising low itch and easier handling — Earthwool’s SoundShield and standard batt ranges are the more comfortable choice for DIY installers and professionals working with insulation daily.
Irregular or wider wall stud spacing — Pink Batts’ firmer consistency helps it hold its position without sagging.
Sensitive to smell — Earthwool’s near-odourless profile is the stronger option.
Underfloor applications needing moisture resistance — Earthwool FloorShield is non-hygroscopic and rot-proof, a solid choice for suspended timber floors.

The Verdict

Both Pink Batts and Earthwool are trusted, Australian-manufactured glasswool products capable of delivering excellent thermal and acoustic performance. Earthwool’s low-itch, near-odourless formula makes it the more comfortable product to install and live with, while Pink Batts’ firmer consistency gives it an edge in trickier stud cavities. For most standard residential ceiling and wall applications, Earthwool is the easier all-round recommendation thanks to its handling comfort and eco-credentials — but Pink Batts remains a genuinely solid choice, particularly where budget or fit consistency is the priority.

FAQS

No. This is a common myth, but Earthwool uses a natural, formaldehyde-free binder that does not attract termites, vermin, or other pests.

Pink Batts carries a consumer lifetime warranty, while Earthwool carries a 50-year product warranty. Both are strong, long-term guarantees, the practical difference for most homeowners is minimal, since both are expected to last the life of the home.

Bradford Gold, Earthwool and Pink Batts are all high-quality glasswool insulation brands. The right choice generally comes down to handling preference, budget and specific application rather than one brand being categorically superior.

Ceilings, generally. Roof spaces typically account for a larger share of a home's total heat loss and heat gain than underfloor areas, so insulating the ceiling first usually delivers the bigger improvement.

Arthur and team were great. From quick turnaround on quotes to sending the team up and getting the job done in a day. It's already feeling better in the house.

We've had a really good experience with NoGap. After struggling to even get calls back from other providers, Arthur at No Gap was speedy with a quote, communicative, and really helpful in setting us up for our insulation removal and replacement. The work team were lovely, worked incredibly hard, and were on time and cleaned up after themselves. Cannot fault the team, and the house is already feeling more comfortable, and even more quiet with the new insulation.

We recently engaged No Gap Insulation and found the whole process, from quotation through to installation, absolutely seamless. Arthur was my single point of contact throughout — he was professional, responsive to my queries, and made everything straightforward. The work involved removing and disposing of the existing insulation batts and installing new ones. The team was very thorough, and I appreciated being shown clear before-and-after photos to see the difference. Overall, an excellent experience — highly recommended.

We highly recommend the guys at No Gap. Good price, great service. After one month we can already see the savings on our gas bill and feel the difference it makes inside. We should have done this years ago..
